Команда: delete
If you want to delete, for example, only .bak and .tmp files

in a directory tree, within sub folders names tmp or save, then sfk delete helps with its very flexible file selection syntax. Free open source command line tool for Windows, Mac OS X, Linux and Raspberry Pi.
sfk delete dir ext1 [ext2 ...] [-yes]
sfk deltree targetdir [-yes]
sfk del -dir dir1 dir2 -file .ext1

delete files or dirs, even if they're write protected.
deltree or rmtree deletes a directory tree with all contents.

options
   -yes          really delete the files. without option -yes,
                 del only lists the files that would be deleted.
   -withdirs     if you supply a file mask other than "*",
   or -wdir      and file deletion leads to an empty directory,
                 then the directory is removed as well. if you
                 supply no file mask (or "*"), then every
                 empty directory is always deleted. this option
                 cannot be used with chaining, as chaining passes
                 only filenames, but no processed directory names.
   -hidden       include hidden and system files.
                 this option is default when using deltree.
   -quiet        print nothing
   -stat         show statistics even with -quiet
   -stoponerr    stop chain execution if delete is incomplete.
   -retry=n[:d]  if delete fails, retry up to n times waiting
                 d ms inbetween. default with deltree (not del)
                 is -retry=2:100

command return codes
   rc 0 : ok all deleted
   rc 5 : delete incomplete
   rc 9 : sfk rc with -stoponerr

lazy confirmation on command chaining
   if you selected files in a command chain, then want to add +del
   you may type "+del." (with a dot) or "+del!" (windows only)
   instead of "+del -yes" to actually delete the files.

examples
   sfk del -withdirs src .bak
      deletes .bak files within src and all subdirs.
      if a directory contained only .bak files,
      it is deleted as well.

   sfk del -yes -withdirs -hidden tmp
      delete tmp with all files, including hidden files.

   sfk deltree. tmp
      the same as above, with "." as a short for -yes.

   sfk list -dir src -file foo*.hpp +del
      first list target files, then add +del

   sfk fromclip +del
      take a list of filenames from clipboard and delete them.
      see "sfk help shell" on how to configure your windows
      command prompt, to allow easy copying of filename lists.
example with output:

   I plan to delete all .bak files in directory tree "src1",
   and all .tmp files in  directory tree "src2":

   sfk del -dir src1 -file .bak -dir src2 -file .tmp
   
      [simulating:]
      DEL : src1\FooBank\BarDriver\include\BarGlass.bak
      DEL : src1\FooBank\BarDriver\include\BarMug.bak
      DEL : src1\FooBank\DB\include\DBController.bak
      DEL : src1\FooBank\GUI\include\FooGUI.bak
      DEL : src2\FooBank\BarDriver\include\BarGlass.tmp
      DEL : src2\FooBank\BarDriver\include\BarMug.tmp
      DEL : src2\FooBank\DB\include\DBController.tmp
      DEL : src2\FooBank\GUI\include\FooGUI.tmp
      10 files would be deleted. 
      [say -yes, -del. or -del! to execute.]

   But I see: oops, I want to keep DBController.bak as it may be
   needed later... same applies for FooGUI.tmp. No problem -
   above is just a simulation, so nothing happened yet.

   I adapt the command to:

   sfk del -dir src1 -file .bak !DBCon -dir src2 -file .tmp !FooGUI

      [simulating:]
      DEL : src1\FooBank\BarDriver\include\BarGlass.bak
      DEL : src1\FooBank\BarDriver\include\BarMug.bak
      DEL : src1\FooBank\GUI\include\FooGUI.bak
      DEL : src2\FooBank\BarDriver\include\BarGlass.tmp
      DEL : src2\FooBank\BarDriver\include\BarMug.tmp
      DEL : src2\FooBank\DB\include\DBController.tmp
      8 files would be deleted. 
      [say -yes, -del. or -del! to execute.]

   The result looks OK, so I add "-yes" to really delete the files.
